Physical parameters of the MX Her eclipsing binary system obtained from BVRI photometry
Abstract
The paper presents preliminary results of the analysis of multicolored BVRI photometry of the MX Her star. MX Her = TYC 3519-1418-1 is an Algol-type eclipsing binary system with an orbital period P =2.3476536 days, showing signs of pulsational instability of the main star. The observations were carried out in 2022 on the ZEISS-600-East telescope, put into operation in the same year at the Maidanak Observatory (Uzbekistan) in the framework of international cooperation with the Yunnan Observatories (China). In this paper, solutions of multicolored light curves using the PHOEBE software are presented for the first time. As a result of the simulation, we obtained the following estimates of the system parameters: the photometric mass ratio of the system M 2 /M 1 = 0.31, the ratio of effective temperatures T 2 /T 1 = 0.57, the inclination of the orbit i = 83.8 ◦ and the eccentricity e = 0.0008.
